Perth has no tide station nearby: this tide is calculated with a global ocean model. It is approximate (it may differ from the real tide by a few minutes and inches) and not for navigation. How we calculate it
Today there are high tides at 1:26 am (9.8 ft) and 1:54 pm (8.2 ft) and low tides at 8:04 am and 8:19 pm. Tide coefficient 84. Right now the tide is rising toward the high tide at 1:26 am. In Perth the tide is semidiurnal: two high and two low tides a day, of similar height. The next spring tides: from November 9 to 11.

Tide coefficient 83 for the 1:26 am high tide and 84 for the 1:54 pm high tide. Average coefficient. The water rises and falls 18.1 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?
Heights above mean sea level. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation.

Perth has no tide station nearby: its tide is calculated with the global FES2022 model, from the nearest model cells offshore (the first one 11 mi away). It may differ from the real tide by a few minutes and inches, and more with wind or storms. Heights are above mean sea level, not chart datum, so low tides are negative. Not for navigation. Model attribution: FES2022 Tide was produced by LEGOS, NOVELTIS and CLS, funded by CNES, and distributed by AVISO (https://doi.org/10.24400/527896/a01-2024.004), AVISO licence (https://www.aviso.altimetry.fr/fileadmin/documents/data/License_Aviso.pdf).
